Will get hands on and understanding of Object Oriented Design SOLID design principles

Will get hands on and understanding of Object Oriented Design SOLID design principles

Build a mental model of test first ways of solving Object Oriented (OOPS) and Low Level Design Problems (LLD)

Understand & implement Test Driven Development (TDD)

Aid in cracking OOPS, LLD & TTD interviews

Aid in cracking top tech interviews of companies such Amazon, GoJek, Thoughtworks , Microsoft & MAANG league ones

Requirements

Description

Test first way of implementing SOLID principles, Design Patterns, and solving LLD problems.BenefitsUnderstanding Object Oriented designBuilding a mental model to crack LLD/OOPS problemsHelp to think in a test-driven wayHelp in designing the architecture of the systemLearning ObjectivesSOLID principlesDesign PatternsApproach LLD / OOPS ProblemsTest Driven Development (TDD) & Clean CodeSteps to crack problems in tech interviewIntended LearnersFull Stack, Backend developer & Tech ArchitectsCandidates interviewing for top tech interviewsCS graduatesClean coding & TDD enthusiasticCourse StructureSection 1: SOLID PrinciplesDefine: Will define one by one each solid principle.Test: Implement banking app via TDD (Test Driven Development). Will start by writing the requirement in the form test and then will fix/implement it.Implementation: Implement solution & improve design using SOLID principle and test should remain fixed after it or can implement new requirement using the principle.Section 2: Design PatternsDefine: Explain the design pattern with a real-world exampleTest: Lay down business requirements via writing testImplementation: Fix the test / implement requirement by applying that design patternSection 3: Shopping CartDefine: Explain the problemThink: Think solution & write down a rough structure of it. Suggest possible actors & their behaviorsTest: Start coding. Write down one by one requirement as a test.Fix: Fix the test incrementally & code the whole solution via it. Use principles & best practices.Section 4: Parking LotDefine: Explain the problemThink: Think solution & write down a rough structure of it. Suggest possible actors & their behaviorsTest: Start coding. Write down one by one requirement as a test.Fix: Fix the test incrementally & code the whole solution via it. Use principles & best practices.
